[Silvio.Falconi]

local cString:=""
aLines := hb_ATokens( cString,"|" )

?len(aLines)


give me 1 instead of zero

why ?

give me 1 instead of zero

Because that is the correct answer.

Code: Select all  Expand view

aLines  := HB_ATokens( "one", "|" )
? aLines // -> { "one" }

I not Know how I Have on String
now I made

aLines := hb_ATokens( cString,"|" )
if empty(aLines[1] )
alines:= {}
Endif

Code: Select all  Expand view

aLines := hb_ATokens( cString,"|" )
if empty(aLines[1] )
alines:= {}
 

This doesn't help either.

ok and if the cString is empty ( i not Know what is on Cstring, so it can be also empty) How set alines ?
because then I must set another two array from alines

oImage:=array(len(aLines)+1)
aImages:=array(len(aLines)+1)

how I can resolve ?
